Detailed Description

A node handle used when a value is kind::object to access elements of the object in potentially destructive manner.

This makes it possible to modify the contents of a node extracted from an object, and then re-insert it without having to copy the element.

Member Function Documentation

bool jsonv::object_node_handle::empty ( ) const

inlinenoexcept

Returns

true if the node handle is empty; false if otherwise.

key_type& jsonv::object_node_handle::key

(

)

const

Returns a non-const reference to the key_type member of the element.

Exceptions

std::invalid_argument

if the node handle is empty.

mapped_type& jsonv::object_node_handle::mapped

(

)

const

Returns a non-const reference to the mapped_type member of the element.

Exceptions

std::invalid_argument

if the node handle is empty.

jsonv::object_node_handle::operator bool ( ) const

inlineexplicitnoexcept
